In the installation and use process, when the electrodes are subjected to external construction force, strong wind acting force, electric arc electromagnetic force, lead vibration and the like, the electrodes can be displaced, so that the gaps among the electrodes are changed. If the gap is increased, the gap is difficult to arc when the ground wire is struck by lightning, and the lightning can not be effectively prevented; if the gap is reduced, the discharge frequency increases, so that the power loss increases, affecting the power communication.

The existing gap fixing mode is mainly applied to an iron cap or an iron cap electrode. By leaving a projection when casting the iron cap as in patent document CN201921809328.2, by casting two apertured plates on the iron cap for fixing the iron cap electrode, etc. as in patent document CN201921471599.1, the structure of the iron cap, etc. needs to be modified, the manufacturing process is increased, and the gap distance is difficult to adjust after the electrode is installed.

Referring to fig. 1 and fig. 2, an embodiment of a ground insulator electrode fixing ring structure includes: the insulator comprises an insulator main body 1 and a fixing ring 2; the insulator main body 1 includes: an iron cap 11 and an iron cap electrode 12; the fixing ring 2 includes: an inner ring 21 and an outer ring 22; the inner ring 21 is sleeved on the iron cap 11, and the outer peripheral wall is provided with a plurality of protrusions 23; the outer ring 22 is sleeved on the inner ring 21, and the inner peripheral wall is provided with a plurality of grooves 24 matched with the protrusions 23; the iron cap 11 electrode is mounted on the outer ring 22.

By arranging the protrusion 23 and the groove 24, the inner ring 21 and the outer ring 22 are mutually engaged after being installed, so that when the iron cap electrode 12 generates deflection fluctuation under the influence of external force, deflection resistance is generated, and the deflection degree of the iron cap electrode 12 and the outer ring 22 is reduced.

Further, the inner ring 21 and the outer ring 22 have elasticity. And the diameter of the inner ring 21 is smaller than that of the iron cap 11, so that the inner ring 21 can be sleeved on the iron cap 11 through stretching and plays a fastening role through elasticity.
